ROLLING-MILL TABLE.

Application filed May 1 5,

A further object is to provide a table haw ing the novel construction, design: and combination of parts hereinafter described and illustrated in the accompanying drawings.

In the drawings: 1

Figures 1, 1, 1 and 1 combine to show a complete view of a table constructed In accordance withthis invention.

Figure 2 is a plan view of one of the spiral conveying rollers. I

Figure 3 is an end View thereof.

Figure 4 is a framentary view of one of the apron plates showing one of the rests in osition.

E igure 5 is a fragmentary transverse sectional elevation through one of the apron plates and rests.

Figure 6 is a sectional view through one of the apron plates and showing a side elevationof arest.

Referring more particularly to the drawings, the numerals 2 and 3 designate parallel supporting beams which extend the ent1re length of the table, and the numerals 4 and 4 designate a series of other supporting beams which extend parallel with the beam 3 and are spaced successively greater distances therefrom. A beam 5 extends parallel with and is positioned between the beams 3 and endmost beam 4; nearest the rolls A.

A plurality of plain rollers 6 are mounted on roller shafts 7 journaled in'bearings 8 on the beams 2 and 4, and extend across the entire table. 7

A plurality of roller shafts 9 are journaled in bearings 10 on'the beams '2 and 4*, and have rollers 11 and 12 thereon, the rollers 11 being between the beams 2 and 3 and the mounted on shafts 18 journaled in bearings 1926. Serial No. 109.311.

19 on the beams 2 and 3, and a series of spiral rollers 20 and 21 are mounted on shafts 22 journaled in bearings 23 on the beams 3 and bearing supports 23*.

The shafts 7, 9 and 18 are all connected by beveled gears 24 with a main drive shaft 25, while the shafts 22 of the spiral rollers 20 and 21 are connected. by beveled gears 26 with a drive shaft 27 operable independent of the drive shaft 25.

The spiral rollers 20 have a pair of righthand splral flanges 28 on their periphery,

while the spiral rollers 21 have a pair of left-hand spiral flanges 29 on their periphery, and the shafts 22, having-the righthand spiral rollers 20 thereon, are adapted to be rotated counter-clockwise, while the shafts 22, having the left-hand spiral rollers thereon, are adapted to be rotated clockwise for a purpose to be described.

The spiral flanges of the pairs of flanges 28 and 29 are adapt-ed to overlap, and to extend around approximately three-quarters of the periphery of the rollers 20 and 21.

The space between the ends of the spiral flanges 28 and 29 on the rollers 20 and 21 is provided with guide-lugs 30, and 30 adapted to guide the sections being conveyed longitudinally of the table between the beams 2 and 3. The lugs 30 cooperate to form a bell mounted guide on each of the rollers 20 and 21 to guide the sections as they are moved into position over the rollers prior to being transferred onto the rest-s (to be described), while the lugs 30 serve to guide the sections after they are removed from the rests and are being conveyed from the table. r

A plurality of apron plates 31 extend from the beams 2 to 4 between the rollers 6 adacent the rear end of the table, and the space between the beams 3 and 4 opposite the last two rollers 20 and 21 at the rear end' of the table is filled by short apron plates 31. Other apron plates 31 extend from the beams 2 to 4 between the rollers 6 and are recessed to fit around the rollers 17. The intermediate portion of the table,which is provided with short feed rollers 11 and 17 and feed rollers 12 is provided with apron plates 31 between the rollers 11 and 17 and other apron plates 31 between the rollers 12. The forward end of the ltable is -also provided with apron plates 31 between the rollers 11 and 17 and with apron plates 31 between the rollers 12, while an inter mediate set of apron plates 31 are bridged between the beams 3 and 5.

The apron plates 31, 31 and 31 are provided with square holes 32 to receive the square mounting lugs 32 projecting from the bottom of rests 33. The rests 33 have inclined end portions 34 and 35 and a flat rest portion 36 ada ted'to be elevated above the eriphery of al of the conveying rollers, so t at when a rolled section. is positioned thereon, the rollers may rotate freely without causing longitudinal movement of the section.

The lugs 32- of the rests 33 are provided with transverse openings 37 adapted to re ceive a wedge 38 to hold said rests in POSI? tion. A stop member 40 is sitioned adjacent the roll end of the tablze to. automatically position the sections on the portion of the table between the, beams 2 and 3 and prevent longitudinal movement thereof until the sections have been moved ofi of the rests 33.

g In 0 veyed ration, the rolled sections are con y the rollers 6 and 12 along the table in a direction away from the rolls A and are directed onto the section of the table between the'beams 2 and 3.

The rollers 6 and 11 are then operated to reverse the direction of rolled sections and move them along the table toward the rolls A. Thes iral rollers20 and 21 remain stationary uring the operation of the rollers 6 and 11, and the guide-lugs 30 on the spiral rollers 20 and 21 serve to guide the rolled sections.

After the rollers 6 and 11 have movedthe rolled sections forward against the stop 40, their rotation is stopped and the spiral rollers 20 and 21 are operated. As the spiral rollers 20 and, 21 ma e one-complete revolution, the-spiral flan es 28 and 29. engage the rolled section an move it transversely onto the rests 33 to permit it to cool. The rollers 6 and 11 are-then operated to bring another rolled section into position on the section of table between the beams 2 and 3. a After the second section is in position, the

spiral-rollers 20 and 21 are again operated 'tolmove a third rolled section'onto the table between he beams Zand 3, and a the same time to move the cooled section forwardly into the bite of the rolls A. The operation .will then be continuous, one rolled section being moved onto the section of table between the beams 2 and'3, while the other is leaving the table, and one section always being positioned on the rests 33 to cool.

The rollers 20 and 21 are rotated in opposite directions so as to counteract each other and prevent longitudinal movement of the rolled sections thereby.

The operating'and control means for .the several rollers may be of'any standard design and the.rollers may be manually or automatically controlled as desired.

The main feature of the invention is the provision of the spiral rollers 20 and 21 and rests 33, whereby the rolled sections are permitted to remain on the table for cooling and whereby a relatively short table may be used.

While I have shown and described one specific embodiment of my invention, it will be understood that I do not wish to be limited thereto, since various modifications may be made without departing from the scope of my invention as defined in the appended claims.
